try a different approach too.. think about the idea that drinking should not be AGE-related. Age is meaningless and is not a valid criterion depending on the individual.
There should be criteria such as being able to vote first, then an established job with 5 year's experience so that you can pay your fines for public intoxication, dui's and drunk & disorderly conduct, not to mention financial responsibility insurance premiums that follow dui's.
If you are going to drink irresponsibly then you should at least be able to pay for its consequences.
NO, I am not saying that you should be allowed to drink if you can afford to pay the fines and such.
The biggest criterion that is not age-related is American Business. How many bars and convenience stores are there per square mile versus the number of schools and churches??
Take 100 grown-ups and have 2 "Sales". One would be all the eductional books and Bibles you can buy at 80% off, and the other would be 80% off the price of a drink at a Bar or local store.
Take a wild guess as to which one would sell out first???? How many churches and schools are getting closed down these days vs. the number of bars in your area???
Our priorities in this Country are all wrong..
